Energy-efficient and environment-friendly liquid sodium silicate production technology and processing equipment

Abstract

An energy-efficient and environment-friendly liquid sodium silicate production technology comprises the following steps: step A, filling materials; step B, dissolving; step C, detecting; step D, discharging materials; step E, cooling; and step F, purifying. Liquid sodium silicate processing equipment comprises a boiler, a liquid sodium silicate processing device is fixed on one side of the boiler, and a high-temperature liquid sodium silicate cooling and discharging device is arranged on one side of the liquid sodium silicate processing device. By arranging a liquid sodium silicate processing device and a high-temperature liquid sodium silicate cooling and discharging device on the side part of a boiler, a large amount of solid sodium silicate can be dissolved, cooled, and discharged. Compared with the conventional dissolution kettle and static pressure kettle, the liquid sodium silicate processing equipment has the advantages that the dissolution of sodium silicate is quick, the energy is saved, and no scale is generated in the dissolution container. Moreover, the sodium silicate with high modulus is dissolved by steam, thus very little high silicic acid polymer is generated, and the liquid sodium silicate is uniform after dissolution.

Description

technical field [0001] The invention relates to the field of chemical processing, in particular to an energy-saving and environment-friendly production process and processing equipment for liquid natron, which is used for processing solid natron into liquid natron. Background technique [0002] Sodium silicate, also known as sodium silicate, water glass, its molecular formula is: Na 2 O n SiO 2 or Na 2 O n SiO 2 · m H 2 O: The abatine produced in the abatine processing plant is all solid abatrine, one is for the convenience of storage and safety, and the other is for the convenience of transportation, but in many cases, it is necessary to process the solid abatrine into a liquid There are two kinds of common equipment for processing solid sodium sodium into liquid sodium sodium in the market: dissolving kettle and static autoclave. Among them, the dissolution kettle, when the modulus is less than 3, the efficiency is low. High (sodium naphthalene is made of Na 2 O and ...

Problems solved by technology

[0003] Chinese invention patent CN 101508441 B discloses a direct dissolution process of molten sodium silicate. The direct dissolution process of molten sodium silicate is to directly flow the liquid pure sodium silicate in the molten state into the dissolution roller, and the The water undergoes hydration reaction, and the molten pure sodium silicate at high temperature is used to directly heat the water and use high temperature water to dissolve the liquid pure sodium silicate. This dissolution method is suitable for bubble flowers with higher modulus Alkali is not easy to dissolve. Due to the high silicon content of high film number foam alkali, its hydrolysis rate is greater than the dissolution rate, and the hydrolysis produces high silicic acid polymer (that is, silica gel) to form precipitates and adhere to its surface. High silicic acid polymer is A viscous white large block, the effect of water quenching is not obvious, and when the amount is too large, it will block the hole on the elbow, resulting in poor discharge
